Florida Live Oak Tree Ring Chronology from 137 to 42 BCE

179 years of tree ring data from live oak trees in Florida, used for paleoclimate reconstruction. The dataset was archived by NOAA NCEI's World Data Service for Paleoclimatology and is associated with a study by Stahle. The data was last updated in the repository in 1992.

Use Cases

• Reconstruct annual climate variables like precipitation or temperature for Florida using the tree ring width chronology.
• Calibrate the tree ring series against instrumental records using the calendar years before present (BP) time index.
• Analyze growth patterns and climate sensitivity of Quercus virginiana (live oak) from the specified geographic location.
• Compare this chronology (ITRDB FL002) with other regional tree ring datasets to study spatial climate patterns.

Strengths

• Covers a continuous 179-year period from 137 to 42 BCE.
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.
• Provides a dated proxy record for a climatically sensitive region (Florida).

Limitations

• The dataset is temporally stale, with no updates indicated since its 1992 repository publication.
• The sample size (number of tree cores or series) is unknown, limiting assessment of statistical robustness.
• Limited to a single species and location, reducing generalizability for broader regional analysis.
